track 27 is a track that I designed with small crests a dips in spots that would try to unsettle a car, most notably the drops at the apex of T1 and 7. track is clockwise and scale is 1cm=30m, giving the front straight a length of 600m(20cm). I think I made the pitlane a little too long, but I have been watching races with cramped pit conditions like 24H nordschleife with 160 cars in a 30 garage pit.

track 28 is an anti-clockwise circuit with a last corner that requires commitment to get the best run onto the S/F straight, but will most likely be skipped for the chicane. scale is 1cm=30m giving the front straight from the chicane a length of 540m (18cm).

ok, first post on this forum for 2018, track 29 is an anti clockwise circuit with an east and west variant which have a similar T1 and can be run at the same time. the combined circuits main straight is the east circuits main straight. the scale is 1cm=25m, giving the S/F straight a length of 425m (17cm).

Given the final corner of the East and main circuits is a chicane, why have the a chicane breaking up the south straight. Judging by your scale it would be around 850=900m. If land was an issue (size of available run off), then the final chicane could be brought a forward up the straight a bit.

ok, ive made a mistake, the main circuit is on the west, I had the paper upside down when I submitted this

as for SBF's point, I think I did that to better separate the west from the main circuit. also the final corner was just going to be a straight up 90, but I changed my mind for a reason I cant remember, perhaps on impulse.
